Code No. U1195: Coding not completed



caution
  • If diagnosis code No. U1195 is set, diagnose the CAN bus lines.
  • When replacing the ECU, always check that the communication circuit is normal.

TROUBLE JUDGEMENT


If the vehicle information data is not registered to the combination meter, the multivision display sets diagnosis code No. U1195.

JUDGEMENT CRITERIA
